AI-Powered supplier vetting

SummaryAMANDA INTERNATIONAL PRIVATE LIMITED is identified as both a trading company and manufacturer/factory in Liaoning, China. It reports wollastonite productivity of 10,000 tons and flexible customization, with 51%–70% of total sales from exports and two years of export activity. However, the investigation identifies substantial documentation and service gaps: no available R&D audit documents, zero R&D patents, no new products in the past year, no ODM, SDK, overseas warehouse, showroom, agent or branch services, and no in-stock capability. Supplier-service assessment and corrective-action procedures are undocumented, while complaint-handling procedures and quality-assurance status are also insufficiently evidenced. Financial records are referenced by year, but no substantive financial performance information is provided.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, operating as a limited company in Anshan, Liaoning, China. This supports a mixed trading and manufacturing business model, but the slice does not establish the relative scale of either activity.

After-Sales capabilityThe supplier has an R&D engineer responsible for technical after-sales support, and reported peak- and off-season lead times within 15 workdays. However, it lacks in-stock, overseas warehouse, showroom, agent/branch capabilities, and written procedures or records for service-capability assessment, corrective actions, and complaint handling.

R&D capabilityInnovation evidence is weak: the supplier reports no new products in the past year, no ODM service, no SDK, zero R&D patents, and only one R&D engineer. Although the engineer is assigned new-product development and technical support, the lack of R&D documentation and outputs indicates a stated deficiency in demonstrated innovation capability.

Production capacityThe supplier identifies itself as a manufacturer/factory and reports annual wollastonite productivity of 10,000 tons. It also has export capability through agents and self-operated import/export rights, but has no in-stock service capacity and raw-material traceability status is unknown.

Customization capabilityThe supplier explicitly reports flexible customization and states that it integrates surrounding resources, including Lithium China stone and zirconium replacement products, to address different customer needs. This supports customization and broader product-resource coordination, although no specific customization examples or technical scope are provided.
